Green roofing has become really popular in recent years due to its environmentally friendly nature. Some folks decide to change portions of their existing roofs to green roofing, but the problem is, they often underestimate the volume of work required.
There are many benefits to having a green roof, but there are also time and money considerations which need to be carefully thought through. We have put together these green roofing tips to help you make the best decision for your property.
Benefits of Green Roofing
There are many benefits to opting for a green roof, which include:
- Increased roof lifespan
- Reduced energy use, as your house, will remain cooler in the summer months
- Reduced risk of flooding and water damage, as a green roof absorbs rainwater
- Added value to the home
- Improved aesthetic appeal of your property
Things to Remember
There are many things to consider when changing part of your existing roof to a green roof. We will take a closer look at these below.
Think about the Logistics
We often say on this page that every roof is different, and this fact is very true regarding the installation of green roofing. The right materials will be determined by the type of roof you have, the existing drainage, as well as the climate and exposure to the elements. Think very carefully about all these elements before starting.
Let’s Talk about Drainage
As mentioned above, there are many factors that you have to consider when choosing to invest in a green roof. One of the critical areas is drainage, which can cause many issues if you get it wrong. The plants have to work alongside the drainage systems. If you don’t have adequate drainage, then the green roof will not be able to sustain itself, which could lead to the plants dying off.
If you decide to install green roofing by yourself, then the first thing you need to determine is if you have the right tools for the job.
Then you need to ensure that the roof is strong enough to handle the extra weight. You have to be 100 percent clear on this before diving in. The green material will weigh between 60 and 150kg before you add any water or snow to it, so you are asking your roof to do a lot of extra work. If you are not sure about how this will all work at this stage, then it would be a good idea to get a professional opinion on it.
Depending on the type of job you are developing, you will need:
- Waterproof liners
- Root membranes
- Wood chips
- Compost and plants!
Time and Money
Whether you decide to do it yourself or hire a roofing contractor, installing a green roof will have to be viewed as a long-term investment. As you can see, it can be quite a tremendous job, so it is well worth considering whether you can do the job properly yourself. Either way, a roofing contractor will be able to help with installations or advice.
